Resounding Persimmon

#b33718
Notes

Resounding Persimmon (#B33718) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (12°, 76%, 40%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resounding
adjective

Latin resonāre, to echo back — present-participle of resound. As a color modifier, resounding implies a saturated-and-echoing-and-imposing quality where the hue reverberates visually like a cathedral-bell ring. Sits at the bold-and-resonant end of the grid, parallel to resonant and booming in usage.

Persimmon
noun

Diospyros kaki, the East Asian persimmon — a fruit eaten ripe from the tree in Japan since at least the eighth century, where its color is named kaki-iro. The fall color of the unblemished astringent fruit: a dense, slightly red orange with the velvet finish of a wax-skinned Hachiya. Closer to maple syrup than to citrus, with the patient warmth of a fruit that takes a hard frost to sweeten.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
